CARBURETER.

SPECIFICATION forming part of Letters Patent No. 685,235, dated October 22, 1901.

Application filed September-l1, 1900. Serial No. 29,329. (No morlel-l f To (ZZZ whom, it may concern.- Be it known that we, MANZAL R..GROMER and ALFRED M. WRIGHT, of McFall, in the county of Gentry and State of Missouri, have invented certain new and useful Improvements in Carburetors, of which'the following is a specification.

Our invention relates to that class of hydrocarbon-gas generators in which the'liquid' fuel circulates around a burner and the gas formed thereby ascends to a carburetor, from which it is conducted to the points of consumption.

The object of our invention is to produce a; gas-generator of simple, cheap, and durable construction and which will be satisfactory and reliable in its operation at all times.

With this objectin view our invention comprises certain construction and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings,in which corresponding numerals refer to corresponding parts, Figure 1 is an elevation of an apparatus embodying our invention. Fig. 2 is an elevation of the lower part of the same from a point of view opposite that of Fig. 1, certain parts being in central vertical section. Fig. 3

- is a central vertical sectional view of the car lix, having its turns increasing in diameter from above downward, as shown in Fig. 2. From the lower end of said coil the tube extends laterally, t-hen upwardly, and passes through plates 1 and 2. A valve 15 intersects said tube above these plates, and above valve 15 the nozzle 16 is connected, preferably by screwing the lower end of the nozzle into the valve-coupling. Said nozzlehas a central vertical perforation therein,tapering upward to a fine capillary opening, as indicated by dotted lines in Fig. 2. A wire 18 (or short pieces of wire) is inserted in the tube 14 in order to increase the surface exposed to the liquid and -of tube 23. with a detachable ring or collar 28 and a dcto reduce the cross-sectional area of the passage through said tube. Below 'platel is a sheet 3 of asbestos or other heat-insulating material, held thereto by a metal plate 2. Shoulders on rods 5 abut against plate 2', and the ends of the rods are screwed into' plates 1 and 4.

Plates'l and 2 have an opening therethrough, and plate 1 has an annular flange 35 around said opening, and this flange is embraced by the' lower end of the chimney-tube :an outer tube 23', secured thereto at 24, a frusto-conical canopy, a drum 27, and a smaller drum 29 adj ustably mounted on the lower end The outer drum 27 is provided tachable bottom plate 37. Said plate 37 has a central circular opening 30 therein, through which the nozzle 16 extends when said plate rests on shoulder 39, Figs. 1 and 2. A circular piece of wire gauze or netting 31 is secured to collar 28 and has a central opening that fits around tube 23. The inner adjust able drum 29 carries across its lower end a piece of wire gauze or netting 32, provided with an opening 33 concentric with opening 30 in plate 37. The lower end of inner tube 21 has a short extension 22 slidingly mounted therein, (or thereon,) and arms 38 are socured to said extension for holding it concentric with tube 23. Tube 21 is provided with openings 34 below the point 24. The canopy 25 has its collar 26 slidingly mounted on tube 23, so that it may be adjusted vertically with respect to the outer drum 27.

Tube 21 extends up to the ceiling or to some 14 is hot valve 9 is opened, thereby admitting liquid to the coil in which it is vaporized. \Vhen valve is opened, the vapor passes through nozzle 16 and upward through carbureter tube 21. Inner drum 29 may be raised or lowered, so that gauze 32 may rest on the shoulder 17 of tip 16 or may hang above said tip. Air is drawn into canopy and through netting 31 down to the bottom of drum 27, thence up through netting 32 and mingles with the ascending hydrocarbon vapor. Canopy 25 acts as a valve for admitting more or less air to the apparatus, being adjustable vertically on tube, as aforesaid. The chimney-tube 19 may be extended to any suitable point. It carries off the greater part of the heated air and gas rising from the burner 12. The downwardly-projecting flange 36 of plate 1 aids in directing this heated air into the chimney 35.

The construction and operation of our invention having been set forth, it is to be understood that certain modifications in details or arrangement of parts may be made without departing from the spirit of the invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a hydrocarbon-gas generator, a frame comprising an upper plate having a downwardly-extendin gperipheral flan ge,a metallic plate secured to the lower side of said upper plate, a sheet or layer of asbestos or the like held between said plates, rods or bolts for supporting said plates, and a base-plate secured to said rods or bolts; substantially as described.

2. In a hydrocarbon-gas generator, in com bination with a vaporizing-tube; a tube so? cured vertically above said vaporizing-tube, a larger tube secured around said vertical tube, openings in the sides of said smaller tube, a

tubular extension or drum mounted slidingly on the lower end of said outer tube, a disk of wire gauze or netting secured across the bottom of said extension or drum, a perforation through said gauze or netting above the delivery end of said vaporizing -tube, a still larger drum secured around the lower ends of said tubes, a detachable bottom plate on said drum, a perforation through said bottom plate concentric with the delivery end of said vaporizing-tube, and a disk of wire gauze or netting secured across the upper end of said drum and having an opening embracing said outer tube; substantially as described.

3. In a hydrocarbon-gas generator, in combination with a vaporizing-tube, a drum arranged above said tube, a vertical tube having its lower end within said drum, a sleeve or collar slidingly or adjustably mounted on said vertical tube above said drum, and a canopy having downwardly-diverging sides depending from said sleeve or collar and adjustable thereon, whereby said canopy may be approached to or raised from said drum; substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in the presence of two witnesses.
